METHGD GF MAKNG RADIATOR CORE-S.

Application filed April i3, 192.2. Serial No. 552,240.

This invention relates to radiators such as used for cooling internal combustion engines and the like.

@ne object of the invention isto design a radiator core which can be stamped out of suitable metal, and which can be very cheaply manufactured.

Another ob'ect of the inventio-n is to design a radiator core so that the front, rear, and side walls can be stamped out of a single piece of metal and then formed to shape.

A further object is to provide a radiator core having a maximum area of cooling surface, which can be easily assembled, and which does not require skilled labor in the manufacture thereof.

A further object still is 'to provide a radiator core which can be easily and quickly repaired, and in which sections thereof can be closed so that the radiator will properly function even should one section or compartment thereof be damaged.

`With the above and other objects in view. the present invention vconsists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it

being understood that changes may be made in the form, size, proportion and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

ln the drawings Fig. 1 is a part sectional front view of my improved radiator core.

Fig. 2 is a part sectional side view thereof.

3 is an enlarged fragmentary detail illustrating the manner of securing the ends of the sheet metal together.

Fig. 4L- is an iso-metric view of one of the tubes.

Fig. 5 is a view of the plate punched, but not formed to shape.

Fig. 6' is a top plan view of the top plate.

Fig. 7 is a similar view of the bottom plate.

Fig. 8 is a view illustrating the bending and forming of the plate.

As stated this invent'on relates to radiator cores and particularly to a radiator core which can be very cheaply manufactured. The conventional radiator at present used for cooling internal combustion engines installed in automobiles, trucks and tractors are expensive to manufacture, and difficultV to assemble or repair. The disadvantages l have lovercome in my improved construction.

Referring now. particularly tothe drawing in whichl have shown the preferred embodiment of my invention, l take a large undeveloped. sheet of metal 1, preferably copper, which I stamp to the shape as shown in Fig. 5 of the drawings,v a series o-f openings 2 are 4punched therein in spaced relation as shown, the section 3 Vof this sheet forming the front wall of the radiator core, while the section l forms the rear wall thereof. This sheet is adapted to be bent on the. lines 5 and `6 so that the front and rear walls will be parallel to each other and spaced apart as shown. The section 7 lforms the one side of the radiator, the other side being formed by the sections 8 and 9 which are bent at right angles to the main body on the lines 10 and 11 and form an interlocking joint as clearly shown in Fig. 3 of the drawing. Angles 12 are secured tothe sides of the radiator by means of rivets or the like and are adapted to support the radiator on the automobile frame. The back wall of the upper radiator tank is formed by bending the section 1.8 on the line 14, and thence bending the section 15 on the line 16 at right angles to the section 13 and parallel to the front wall, a suitable intake opening being provided and a connection 17 being secured thereto, the lip section 18 is then flanged outwardly as shown being bent on the line 19. A

The front wall of the radiator is exactly similar, excepting that the section is stra-ight, a lip 2O being provided and is bent outwardly on thev line 21. A perforated plate 22 is then secured in position between the walls and forms the bottom of the radiator top tank, the top plate 23 being welded to these outwardly flanged top and side Vlips as shown. A. water inlet 2e is secured to this top plate and is provided with a con-V ventional radiator cap in the usual manner.

The bottom is formed identically thesame as the top, the lips 25 and 25n being flanged outwardly and bent on the bending line as indicated in Fig', and the plate 27 is welded thereto. The plate 26 is then welded or soldered in place, and forms the top of the radiator bottom tanlnand this plate is also perforated in a similar manner to allow water or otherliquids to enter the bottom tank, outlet pipe 28 being connected thereto in the usual manner.

also presents a neat appearance.

The plate is iirst punched as clearly shown in Fig. 5, and then bent to shape as shown in Fig. S, of the drawings, the openings 2 in the front and rear walls will then bein direct horizontal alinement'and are adapted to be connected by the tubes 29. 'Ihese are preferably7 welded to the respective walls and form passages for the circulation of air for cooling the water circulating through the radiator core.

vertically disposed division plate 30 is secured between each row of tubes and separates the radiator core into separate and distinct compartments,V the openings in the plates 22 and 26 being spaced to allow the water or other liquid to freely flow into each compartment. These tubes can be of any reasonable desired size, and while I have shown but a limited number it will be clearly understood that any desired number can be used. A perforated screen 8l is secured to the front of the radiator by means of the small bolts 32, and serves to break the air current circulating through the tubes ancll t is of course understood that this is merely the radiator core, the shell covering and sur-. rounding the core in the usual manner, the

usual opening being provided in the front of this shell to allow for proper circulation of air.

F rom the Aforegoing description it will be obvious that I have perfected a very simple and improved article of manufacture.

Vhat I claimis l. The method of making radiator cores Y metal7 punching a plurality of openings therein and bending it to shape to form front, rear and side walls, soldering the edges together and then bending a section to form the back wall of the upper radiator tank, then taking a couple of sheets and soldering them on the top in spaced apart relation to yform the top tank, and soldering a couple of spaced apart sheets in the bottom to form the lower tank, then securing a number of vertically disposed spaced apart division plates between the walls7 and soldering tubes in the openings punched in the front and rear walls, and securing supporting angles to the side walls of the shell.

Vfront and rear wall and soldering a top plate to said walls to form a top tank, then soldering a pair of plates to the walls near the bottom to form a bottom tank, securing tubes in the openings in the front and rear wall, and a plurality of spaced apart vertically disposed plates between the walls securing inlet and outlet tubes to the top and bottom tanks, and securing supporting brackets to the side-walls of the radiator shell. l

lIn testimony whereof I atiix my signature.
